The shutout victory was Nashville's PCL co-leading 12th of the season.

The 24-year-old Burgos (2-2) struck out four and walked zero in his fifth quality start in seven PCL outings.

The victory was the Sounds' ninth over the Cubs this season, which gave Nashville its seventh winning season series in the last eight years over Iowa since become a Brewers affiliate in 2005.

Shortstop Eric Farris led the Sounds offense, going 2-for-4 with a homer and a double. Farris' two-hits also moved the infielder past Brad Nelson for 10th place on the Sounds all-time list with 345 hits.

Nashville jumped out to a 1-0 lead in the top of the first inning with Logan Schafer's 10th homer of the season. The long ball to right field was the center fielder's first since July 15 at Albuquerque.

The Sounds pushed the lead to 2-0 in the next frame, beginning with a leadoff walk by third baseman Andy Gonzalez. After right fielder Jordan Brown moved Gonzalez to second on a base hit, Burgos hit a weak sacrifice to the pitcher, who airmailed the throw into the outfield. Gonzalez then walked home from third.

Nashville scored its final run in the bottom of the eighth as Farris belted his career high-tying seventh homer down the left field line off Iowa reliever Jeff Beliveau.

Three Nashville relievers followed Burgos for the combination shutout. Donovan Hand worked around a pair hits for a scoreless inning, stranding both runners in scoring position. Mitch Stetter struck out two in one scoreless inning. Robert Wooten closed out the contest with his seventh save.

Iowa starter Ryan Rowland-Smith (3-6) came away with the loss, surrendering two runs (one earned) on five hits and two walks in five innings.

Nashville and Iowa will “turn back the clock” while the two teams conclude their season series at 7:05 p.m. on Taco Bell Throwback Thursday. Right-hander Claudio Vargas will make his final start of the season for the Sounds against Iowa righty Yoanner Negrin (0-0, 3.60).

The Sounds will be wearing retro 1980s-style uniforms for the final time in 2012. Iowa will be sporting retro green and yellow 1970s-style uniforms representing the Iowa Oaks, which played in Iowa's capital city from 1969-1980.
